Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed October 1,1904. Serial No.226,762.

T 0 a 11/72/0772, it may concern:

Be it known that I, JOHN F. GRACE, a citizen of the United States,residing at New York city, county of Kings, and State of New York, haveinvented certain new and useful Improvements in Condensers, fullydescribed and represented in the following specification and theaccompanying drawings, forming a part of the same.

The object of the present invention is to provide improved means forcollecting the air and uncondensed vapors in the condensing-chamber ofthose classes of condensing systems in which the air and uncondensedvapors, or part of these, are removed from the condensing-chamberseparately from the discharge-water, the especial object of theinvention being to provide a simple and comact construction by which theamount of iquid collected with the air shall be reduced and the aircooled and condensible vapor therein condensed and removed as the airpasses to the air-pump.

For a full understanding of the invention a detailed description of aconstruction embodying the invention as applied in its preferred formwill now be given in connection with the accompanying drawings, forminga part of this specification, and the features forming the inventionthen specifically pointed out in the claims.

In the drawings, Figure 1 is a diagram-- matic elevation of a condensersystem embodying the invention as applied to a common type ofgravity-injector condenser system. Fig. 2 is a central vertical sectionof the condensing-chamber and air-collector. Figs. 3 and 4 are verticaland horizontal sections of the air-collector and cooler.

Referring to the drawings, A is the condensing-chamber; B, thesteam-pipe entering at the top; O, the condensing-water pipe throughwhich the condensing water is forced by the circulating-pump D E, thedischarge or tail pipe of the condenser through which thedischarge-water passes to the hot-well F, and G the air-pipe leadingfrom the condensing-chamber A to the air-pump H. The condensing-waterpipe O enters the lower part of the condensing-chamber A and extendsupward centrally of the chamber, the water being delivered from itsupper end past an adjustable spray-nozzle I, which is ribbed ver ticallyon its periphery and carried by avertical rod 10, movable vertically foradjustment of the nozzle I by being screw-threaded through astufling-box in the steam-pipe elbow, as usual in such constructions.

All the parts thus far described and shown are of a form common in thisclass of condensers; but it will be understood that they may be of anyother suitable form,

Referring now to the means for collecting and cooling the air anduncondensed vapors to which the present invention especially relates,there is mounted on top of the condensingvater pipe C, so that thecondensing water passes upward through it to the spraynozzle 1, a hoodor bell at, extending over a considerable part of the condensing-chamberand open at the bottom to receive the air and uncondensed vapors arisingfrom the lower part of the condenser within the space between thefalling condensing water and the condensing-water pipe O. Within thishood a and inclosing or forming a continuation of the condensing-waterpipe O is a casing I), shown as formed of an inner cylinder 11, throughwhich the condensing water passes, which cylinder is inclosed within asecond cylinder or shell 12, mounted upon the top of the condensing-pipeO, these two cylinders 1 1 12 being formed to provide an air-chamber cbetween-them, this chamber 0 opening to the bell a in the upper part ofthe latter through passages 13, formed in the outer cylinder or shell12. These passages 13 are not formed radially, but inclined to theradius and directed forward in the direction of movement of the air asit passes to the air-pipe G, so as to be approximately tangential to theairchamber, better separation of the liquid from the airbeing thussecured. To direct the air to the openings 13, the forward side of theopenings 13 is protected by a lip or shoulder 1, formed on the shell 12,as shown clearly in Figs. 3 and 4. As many of these openings or lips asdesired may be used, four being shown. At one side of the air-cooler theair-chamber c connects with the upper end of the air-pipe G within thecondenser by passage 14,. Drainpipe 15 connects the bottom of the elbowof pipe G within the condenser with the tailpipe E, so as to carry offthe water condensed from any vapor collected with the air.

For the purpose of better securing the separation of liquid from the airand condensing any vapor entering the hood or bell a with the air aswell as cooling the air the inner side of the bell a is provided withvertical ribs 2,- which aid in separating the liquid from the air andwhich increase the amount of coolingsurface with which the air and vaporengage. The bell and ribs 2 are cooled efficiently by the condensingwater sprayed over the top of the bell a, and the air within the chamberC is further cooled by its contact with the inner cylinder 12, throughthe inside of which passes the incoming condensing water. The top of thebell a or, as shown, a separate plate mounted thereon is preferablyprovided with vertical ribs 16, forming slots through which the water issprayed out sidewise past the spray-nozzle I, so as to fall in a showeron the top of the bell a and within the space surrounding it.

It will be understood that the invention is applicable to condensers ofdifferent classes and that in condensers of the general class of thatshown the condensing-water pipe and air-cooler may be otherwisearranged, this de-.

pending somewhat on the style of condenser to which the invention isapplied. It will be understood also that the invention is not limited tothe special manner in which the aircooler is formed or connected withthe con- (lensing-water pipe, but that the detail construction of theair-collector and cooler may be varied while retaining the featurescovered by the claims.

What I claim is- 1. The combination with a condensingchamber, of an aircollector and cooler therein consisting of a bell opening downwardly, acasing forming an air-chamber within said bell, air-passages connectingthe bell with the air-chamber and inclined forwardly in the direction ofmovement of the air, and an airdischarge pipe connected with saidair-chamber.

2. The combination with a condensingchamber, of an air collector andcooler therein consisting of a bell opening downwardly, a

casing forming an air-chamber within said bell, air-passages connectingthe bell with the air-chamber and inclined forwardly in the direction ofmovement of the air, projections on the inner side of the bell, and anair-discharge pipe connected with said air-chamber.

3. The combination with an injector condensing-chamber and itscondensing-water pipe and spraying devices, of a casing through whichthe condensing water passes to the spraying devices, an air-chamberwithin said casing having its inner side cooled by the condensing water,an air-collecting bell outside said chamber over which the water issprayed, air-passages from said bell to said air-chamber inclinedforwardly in the direction of movement ofthe air, and an air-dischargepipe connected with said air-chamber.

4. The combination with an injector condensing-chamber and itscondensing-water pipe and spraying devices, of a casing through whichthe condensing water passes to the spraying devices, an air-chamberwithin said casing having its inner side cooled by the condensing water,an air-collecting bell outside said chamber over which the water issprayed, air-passages from said bell to said air-chamber inclinedforwardly in the direction of movement of the air, ribs on the innerside of witnesses.
